who v. whom

In grammar, a subject performs an action, and an object receives an action. Who is the subject of a clause, and whom is the object of a clause. If you’re uncertain which word to use when formulating a question, remember that:

• If the question can be answered with the subjective pronouns I, he, she, we, or they, use who.
• If the question can be answered with the objective pronouns me, him, her, us, or them, use whom.

So Queen got it right when they asked, ‘Who wants to live forever?’ (He doesn’t seem to anymore.) But Bo Diddley should actually have been asking, ‘Whom do you love?’ (To which the response would be, ‘I love her’.) If we wanted to get slightly more pedantic and substantially less righteous, AC/DC’s ‘Who Made Who’ could be retitled ‘Who Made Whom’.
